Comparison of conventional anaesthesia, total intravenous ketamine and epidural block for abdominal hysterectomy.

Techniques of total intravenous anaesthesia with ketamine and continuous epidural block are compared with the conventional method of using halothane, nitrous oxide and relaxant. Both ketamine and epidural techniques were associated with minimal cardiovascular disturbances, low blood loss and better quality of anaesthesia and recovery scores. The usual psychomimetic effect associated with ketamine administration was observed in only one patient. Further experience of total intravenous ketamine anaesthesia with adjunctive use of fentanyl to attenuate cardiovascular effects and midazolam for the pyschomimetic effect can further refine the technique. Cerebral function monitoring, if possible, will allow correlation of depth of anaesthesia with drug dosage and can ensure appropriate anaesthetic depth and recovery.

Pain clinic in Goroka Base Hospital: a retrospective analysis.

Over a nine-month period in Goroka Base Hospital 310 patients with chronic pain were treated in the pain clinic. Disabling lower backache was the most common complaint, followed by myofascial disorders and cancer pain. Best results for the management of pain was observed in patients receiving intralesional steroids, followed by intercostal block and lumbar sympathetic block for abdominal malignancies.

Induced hypotension in a smoker.

An episode of hypoxia following the use of propranolol and sodium nitroprusside to induce hypotension in a 50-year-old male patient undergoing craniotomy for frontal meningioma is described. The importance of proper preoperative screening of lung function and intraoperative monitoring of blood gases is highlighted.

Chronic pain management: the role of the anaesthetist.

World-wide more than 4 million people are at present suffering from cancer pain, and many more from other kinds of pain. Pain remains an under-treated and neglected public health problem. Lately technological advances and greater understanding of the physiology and anatomy of pain have helped further progress in pain management but much is still empirical without a scientific basis. Since the fundamental component of the practice of anaesthesiology in the treatment of pain, the anaesthetist is the best person to understand pain and organize pain clinics.

Anaesthesia for phaeochromocytoma resection: role of thoracic epidural blockade.

Two case reports are presented of patients who underwent surgical removal of phaeochromocytoma at Goroka Base Hospital, one with the use of thoracic epidural blockade supplemented with light general anaesthesia. This patient had a much smoother perioperative anaesthetic course than the other, with minimal elevation of blood pressure during the procedure. The paper highlights the value of epidural blockade for excision of phaeochromocytoma, especially in situations where the latest recommended methods and advanced monitoring facilities are unavailable.

Anaesthesia for caesarean section in a patient with Wolff-Parkinson-White syndrome.

The anaesthetic management is described of a patient with Wolff-Parkinson-White syndrome who had to undergo caesarean section due to failed induction of labour. Spinal anaesthesia with hyperbaric nupercaine was given. The main problem encountered during anaesthetic management was repeated attacks of supraventricular tachycardia which were primarily due to anxiety or occurred during pharmacological intervention with oxytocics.

Anaesthesia for repair of neonatal diaphragmatic hernia and eventration: role of ketamine infusion.

Management of neonates with congenital diaphragmatic defects who have symptoms within hours of birth is still unsatisfactory. The mortality reported for these high-risk infants ranges from 20% to 80%. Anaesthesia for repair of these defects is nonetheless the most perilous phase in these conditions. Surgery often worsens the situation with regard to blood gases. The anaesthesia has to fulfil the criteria for neonatal surgery and thoracic surgery with the added components of elevated pulmonary vascular resistance and pulmonary hypoplasia. The mortality figures are worse if there is lack of a proper neonatal intensive care facility. The management of two such cases is discussed with special stress upon use of the ketamine infusion technique as an alternative safe anaesthetic regime.

Anaesthesia and surgery in sepsis.

Administration of anaesthesia to patients with sepsis and its effects on the progression of infection in the postoperative period is an important consideration both for surgeons and anaesthetists. All cases of abdominal sepsis carry a surgical mortality of around 50%. Though appropriate therapy is virtually always surgical, limiting initial surgical stress to simple closure and irrigation, supplemented with a proper anaesthetic regime, nutritional care and antibiotic cover, can improve the outcome.

Postoperative epidural morphine analgesia in Papua New Guinea.

In order to introduce the technique of epidural narcotics for pain relief in Papua New Guinea, fifty patients were given low doses of epidural morphine and thereupon the quality of analgesia and morbidity evaluated. The lowest effective epidural morphine dose was determined by considering the patient's characteristics and height of surgical incision. Pain relief was provided for three postoperative days in the surgical or gynaecological wards. The quality of analgesia thus provided was excellent in all the patients with no incidence of clinically significant respiratory depression or hypotension. Minor complications such as nausea, vomiting, pruritus and retention of urine were also relatively uncommon.

Anaesthesia in arthrogryposis multiplex congenita: case report.

The anaesthetic management of an 11-year-old male with arthrogryposis multiplex congenita (AMC) with myopathic features is described. The child presented with an obstructing renal calculus and a pyelolithotomy via an anterior transverse subcostal extraperitoneal incision was performed. In view of the associated hypoplastic musculature, severe scoliosis and expected increased sensitivity to various sedatives and inhalational anaesthetic agents, low-dose ketamine (10-15 micrograms X kg-1 X min-1) was administered by continuous infusion, with a satisfactory result.
